These modules utilize **p-type monocrystalline PERC solar cells**, and their refined interconnection architecture ensures stable performance even under partial shading and uneven irradiance, common in many Polish installations. A key feature is the **glass-glass construction**, which enhances environmental resistance and facilitates maintaining parameters over a long period - a real advantage in projects exposed to wind, humidity, and temperature fluctuations. The series targets **high reliability in challenging conditions** thanks to high-quality lamination materials and robust construction. The YLM 3.0 Plus 1 is a solid choice for commercial and utility-scale PV projects, where dependable power generation and long-term durability take precedence over catalog specifications. ## Notable figures - Efficiency of 21.0% matches the \*\*PERC 550-600W\*\* median - At 210.2 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - At -0.34%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - #9828 for efficiency, #8846 for temperature performance out of 14129 panels ## Questions ### What is the maximum power output of the Yingli YLM 3.0 Plus 1 panel? The top variant of the YLM 3.0 Plus 1 series reaches up to 670 Wp, thanks to 132 large p-type monocrystalline PERC cells. This allows high energy yield from fewer modules, which meaningfully reduces installation time and mounting structure costs in commercial installations and utility-scale PV farms. ### How does the glass-glass construction of the YLM 3.0 Plus 1 differ from standard glass-backsheet panels? Unlike typical panels with a rear backsheet layer, the YLM 3.0 Plus 1 encapsulates its cells between two glass panes. This design better protects the cells from moisture, microcracks, and PID degradation, resulting in a slower power decline over time and greater resistance to harsh weather conditions such as strong wind or hail. ### What warranty comes with the Yingli YLM 3.0 Plus 1 panels? The manufacturer offers a 12-year product warranty along with a 30-year linear power output warranty. This means that after 30 years of operation, the panel should still retain the guaranteed minimum percentage of its initial output, a standard expectation for modern glass-glass modules from a tier 1 manufacturer. ### Is the YLM 3.0 Plus 1 suited for large-scale PV farms or more for residential roofs? This series is designed primarily for commercial installations and utility-scale PV farms, where predictable energy yield and long-term durability matter more than raw datasheet figures. Its large format and high unit power (up to 670 Wp) make it better suited to large mounting areas than to a typical single-family sloped roof. ### Are the YLM 3.0 Plus 1 panels bifacial, generating power from the rear side? No, the YLM 3.0 Plus 1 series uses standard monofacial PERC cell architecture. The glass-glass construction here is meant to boost durability and environmental resistance, not add rear-side power generation - this sets it apart from bifacial models in Yingli's lineup. ### Who manufactures the YLM 3.0 Plus 1 panels, and is it a reliable tier 1 supplier? The YLM 3.0 Plus 1 panels are made by Yingli, a Chinese manufacturer with decades of industry experience, classified as a tier 1 supplier. This reflects solid financial standing and proven manufacturing capacity, which matters when pursuing warranty claims over the multi-decade lifespan of a PV installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1753058813947-0d996e6aa81c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.8 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, +3.6 pp, +5 yr warranty | | [Yingli YL580DF60f/2](https://comparepv.com/panel/yingli-yl580df60f-2) | 580 W | Heavier, -0.5 pp, +5 yr warranty | | [Yingli YL585DF60f/2](https://comparepv.com/panel/yingli-yl585df60f-2) | 585 W | Heavier, -0.3 pp, +5 yr warranty | | [Yingli YL590DF60f/2](https://comparepv.com/panel/yingli-yl590df60f-2) | 590 W | Heavier, +5 yr warranty | | [Yingli YL600DF60f/2](https://comparepv.com/panel/yingli-yl600df60f-2) | 600 W | Heavier, +5 yr warranty | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +85 W, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +80 W, +2.9 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +75 W, cooler, +2.7 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +75 W, +2.7 pp, +5 yr warranty | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +70 W, cooler, +2.5 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +70 W, +2.5 pp, +5 yr warranty | | [Sunpro Power SPDG660-N120M12](https://comparepv.com/panel/sunpro-spdg660-n120m12) | 660 W | +65 W, +2.3 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/yingli-yl595d-41f-1-2-yl595d-41f-1500v-1-2 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
